When Allah sent any Nabi or Rosul in any settlement, he came and invoke the people saying, - “Allah has sent me as His Messenger, Nabi for you”. Then logically people ask, “What is the proof of your being a Messenger or Nabi sent by Allah?” Every rational person will ask it, because it is not the work of a wise and intelligent man to allow a man as the Rosul (Messenger) of Allah only if he claims to be. He must have the evidence in favor of his claim. Allah knows it very well, so Allah gives some conclusive sings, Miracles (Mojeza) to His Messenger for the people to be undoubted about him. [Qur’an: Sura: Al-Emran-183, 184].

This evidence could be of two types. Firstly, rational and intellectual observation with the truthfulness, qualities of character, and speech of the Messenger, people will be able to realize that he is not a common man rather a Rosul (Messenger) of Allah. Secondly, those who are unable to judge with ration and intellect, needs ocular proof. Otherwise they may ask Allah in the day of Hasar (final result day), “O Allah! How will we be able to realize the man as Your sent, who takes food, sleeps, roams everywhere like us?” To demolish the scope, Allah has sent conclusive sings, Miracles (Mojezas) to each and every Messenger. Such as: The Messenger of Allah Isa (AS) said, “I’m the Messenger of Allah.” Observing his movement and doings some realizes him as the Messenger but rests of the Jews don’t believe him. To create faith in them Allah ordered Isa (AS) to make alive a dead man of three days past named Lazarus. In front of many Jews, Isa (AS) said, - “Lazarus, rise.” He (Lazarus) stands up and become alive on the spot. Everybody witnessed the event with their eyes. Does there remain any scope of question after that event whether he is a Messenger or not? But even then they did not trust him. They said, ‘It is a black magic’. They failed to realize it is impossible to animate a man with magic, if do then the magicians made many dead man alive and earns millions of money for each case. Nobody is able to provide soul and life other than Allah. Yet after demonstrating such a patent Miracle (Mojeza), most of the people distrust Isa (AS) as a Messenger of Allah. Such kind of Miracle (Mojeza) is the last step of the confirmation towards the truth, no steps remains out after that. Allah warns those, who distrust even that type of Miracle (Mojeza) – “Then he thought. Then he frowned and he looked in a bad tempered way. Then he turned back and was proud. Then he said, ‘this is nothing but magic from that of old. This is nothing but the word of a human being!” I will cast him into Hell-fire. And what will make you know exactly what Hell-fire is? It spares not (any sinner), nor does it leave (anything unburnt)! ” [Sura: Modasser-21-28]

Allah has sent Mohammad (SM) as the Last Nabi in the continuation of sending Messengers. No Messenger will come after him. For this why, there remains some significant difference in his sending. One of those is, the prior Messenger of him was for the people of a specific, limited territory. Such as, Moses (AS) was sent only for the Pharaoh of Egypt and for the Bani- Eslailes, Isa (AS) sent for the contemporary Bani-Esrailes, Hud (AS) sent only for the nation Aa’d. For this why their Miracle (Mojeza) was not permanent. After their departure from the Earth, nobody could see those Miracles (Mojezas). Also there hasn’t any necessity of that Miracle as the new Messenger brings new Miracle (Mojeza) for them. The stick of Moses (AS) creates path dividing the red sea for the Bani- Esrailes to pass away. One will fail to see the ocean divides again sitting in the bank throughout the life. Like that, we can’t further see the Miracles (Mojezas) brought about by the former Messengers of Allah. Because Miracle (Mojeza) of nobody is stable, those are temporary, time and place dependent.
